Hi.
Sources are a couple of guys I trained with. They did their type rating early last year and have not flown yet. They seem to like Qatar and have a good social life but after having been there over a year they are getting pretty bored. They often use staff travel rates to come back to the UK for a break but I understand they can only do this for a certain period due to tax??
I think they can be called at anytime to report in case their line training is brought forward, but at the minute I believe they won't start until the beginning of 2014.
